To get the fields for the same *time*, you will need to do some
averaging yourself. In particular, each time step first steps H
and then steps E (and D), so the E (and D) field is always half a
time-step ahead of the H field. So,
In two dimensions, the fields (by symmetry since the xy plane is a
mirror plane) can be divided into two polarizations, TE (Hz, Ex, Ey)
and TM (Ez, Hx, Hy). When you use an Ey source, it only produces TE-
polarized fields. You get a magnetic field (and a nonzero stress
tensor), but it is in

To get the fields for the same point in space, you can just use one of
the supplied interpolation routines as defined in the manual, such as
get-field-pt. The HDF5 output routines also interpolate all the
fields onto the same spatial grid. Also, the built-in field-
integration routines
Hi, Steven and Meepers,
Now, I am working on the optical force simulation project. And mostly, the
optical force is presented by the Maxwell stress tensor.
(http://en.wikipedia.org/wiki/Maxwell_stress_tensor).
As you know, Meep is using FDTD algorithms and the E output and H output have
Do these texts answer your question?
